China Magnesia Pricing notice

After a one-month consultation period, Fastmarkets has amended the frequency of its price assessments for MB-MAG-0005 Magnesia, dead burned, 97.5% MgO, lump, fob China, MB-MAG-0002 Magnesia, dead burned, 90% MgO, lump, fob China, MB-MAG-0009 Magnesia, fused, 97% MgO, Ca:Si 2:1, lump, fob China, and MB-MAG-0007 Magnesia, fused, 98% MgO, lump, fob China, to monthly from weekly.

Following a consultation which concluded on Friday May 23, the frequency of the prices will change to monthly from weekly, with the first assessment on a monthly frequency taking place on Tuesday May 27.

The change in frequency will help to better reflect the dynamics of China’s magnesia market, which according to participants has been experiencing lower liquidity.
